WLAN on the mobile phone cannot be disabled (the WLAN switch is dimmed).
Probable causes and solutions:
1. If Wi-Fi is enabled, there will be a slight delay. Please wait for 2 seconds and observe whether it is enabled. Do not click it continuously.
2. Enter the "Settings-Network&internet-Wi-Fi" interface, and try to turn on/off the Wi-Fi switch again.
3. Please turn on/off the flight mode, and restart your mobile phone to see if you can open the Wi-Fi normally.
4. It is recommended that you restore the factory settings after backing up the data. ()If the same directory as the directory where factory default settings are restored has the reset network setting option, you can reset the network setting instead of restoring factory default settings.
If this problem cannot be solved by using the above methods, it is recommended that you carry the handset purchase voucher to the repair office for repair.
